Currently i don't see any current patch notes, the last patch notes are for June and it's currently (and was yesterday, when the update happened) August; https://www.eveonline.com/articles/patch-notes. There are no patch notes for August (yet? I suppose it is yet to be posted then?)
Meanwhile, the launcher looks like this: https://i.imgur.com/DJPzorW.png . There isn't a mention of any dev blog anymore. It's been hidden, as i stated in my OP, 24 hours after it went live. Sure, it still exists, you can find it. But that means the player has to look it up and nobody is going to randomly look up devblogs every time they've stepped away a few days. Something needs to notify the player something changed before that happens.
The changes themselves is not why i created this post; the changes and their intended / expected / subjective results is a whole different can of worms other people can discuss in their posts. The reason i created this post is because any information to the players about this change posted yesterday is already hidden unless you specifically come to reddit (and that source will vanish in a few days too) or look up past dev blogs (which few people do out of the blue). This is just plain bad communication from a game to its players.
Lastly: no offense, but complaining about someone with valid criticism about the way CCP has done something with going "all of a sudden it's REEE" is not really a valid response. Visibly showing changes for people that aren't glued to reddit 24/7 is kind of important, especially (as i mentioned in my original post) during a holiday season where part of the playerbase is basically expected to be gone for a week or more at a time.That's a longer period than the time it took between devblog, changes on the live server and all information being hidden.
My biggest suggestion would be to ensure information about changes to long-established mechanics stay visible in the launcher for at least a week or two, or give an ingame message / notification if it's a "hidden" mechanic like the tax numbers. They're there, but they're tiny and everyone has seen them a million times.
Notable changes are kind of expected to have notable visibility. Hiding all mention of it without digging in deeper, such a very short time after the changes, isn't exactly notable visibility.
EDIT: patch notes exist, i simply didn't notice as they're posted under June, not August, despite it being a patch in August.
